Short Description

The CSJ Crown Drill Bit (4D, Ø15.00-15.99mm) is a high-performance indexable insert drill engineered for high-speed, deep-hole drilling. Featuring an innovative front-locking body and integrated internal cooling, this side-locking drill tip system ensures maximum stability, superior chip evacuation, and exceptional hole accuracy in demanding industrial applications.

Product Features & Introduction

The CSJ Crown Drill Bit represents the next generation of high-efficiency drilling technology. Designed to bridge the gap between solid carbide drills and traditional indexable drills, it combines the cost-effectiveness of replaceable crown tips with the rigidity of a solid tool.

Front-Locking Design: The secure front-locking mechanism allows for quick and precise insert replacement directly on the machine, drastically minimizing downtime.
Internal Cooling System: Dual internal coolant channels deliver high-pressure fluid directly to the cutting edge. This effectively reduces thermal stress, prevents chip packing, and significantly extends tool life.
4D Deep-Hole Capability: Specially engineered flutes easily handle drilling depths up to 4 times the drill diameter ( $4\times D$ ) while maintaining excellent straightness and surface finish.
Side-Locking Drill Tip Stability: The robust side-locking configuration eliminates micro-vibrations, ensuring high repeatability and tighter hole tolerances during high-speed operations.

Product Functions & Benefits

High-Speed Penetration: Optimizes metal removal rates (MRR), significantly cutting down cycle times compared to conventional drilling methods.
Efficient Chip Evacuation: The combination of polished flutes and internal cooling forces chips out smoothly, preventing catastrophic tool failure in deep holes.
Cost Efficiency: Instead of replacing or regrinding an entire solid carbide drill, users only need to replace the crown insert, drastically reducing tooling costs per hole.
High Precision: Delivers excellent hole cylindricality and surface finish, often eliminating the need for secondary reaming operations.

Application Scenarios

This heavy-duty drilling tool is ideal for high-precision, high-volume production across various demanding industries:

Automotive Manufacturing: Drilling engine blocks, crankshafts, and heavy-duty powertrain components.
Aerospace & Defense: Machining tough alloys, titanium, and stainless steel structural components.
Mold & Die Industry: Deep-hole drilling for ejector pin holes and water cooling lines in large mold bases.
Heavy Machinery & Energy: Processing tube sheets for heat exchangers, wind turbine hubs, and oil/gas valves.
Compatible Equipment: Perfect for CNC Machining Centers, Turn-Mill Centers, and specialized deep-hole drilling machines.
